[Android WebView] Scale the layout width by the UA initial scale

Another subtle difference of the Classic WebView implementation. In non-wide
viewport mode, the UA initial scale (set via 'setInitialPageScaleOverride')
can stretch the resulting layout width.

Remove failing tests that are gated on inactive work

These tests were committed by Glenn Adams when he was actively working
on CSS3 line-break. The patch that made these tests pass was rolled out
due to a perf regression in February, but Glenn is no longer working
on the patch. Removing the tests since there's not currently a path
forward.
